WILLIAM THOMAS CALDERWOOD, OF HUDDER SFIELD, ENGLAND.

MACHINE RELATING TO THE MANUFACTURE AND MOLDING 0F SOAP.

Specification of Letters Patent.

Patented Mar. 21, 1922.

Application filed March 10, 1921. Serial No. 451,176;

T 0 all whom it may concern.

Be it known that I, VILLIAMTHOMAS CALDERwooD, a British subject, and resident of Huddersfield, in the county of York, in the Kingdom of England, have invented certain new and useful Improvements in Machines Relating to the Manufacture and Molding of Soap, of which the following is a specification.

This invention refers to improvements in machines relating to the manufacture and molding of soap, and is applicable to the manufacture of soap in bars of various sections slabs ortablets with plain, stamped or otherwise marked surfaces.

The object of the invention is to reduce the cost of manufacture and improve the quality of the product.

Heretofore it has been customary commercial practice to prepare bars of soap by cutting the same from slabs by means of a bar cutting machine, entailing a considerable amount of labour' in handling, excessive waste'of material and great loss of time, due to the cooling of the soap in large soap frames before cutting same into slabs.

Machines have heretofore been designed for molding soap, but according to this invention, and in order to overcome the loss in labour, waste and time besides improving the product the soap is run in liquid form straight from the soap pans or soap crutchers into an improved machine, capable of being warmed by steam, hot water. air or any other method while the soap is being run, also when required cooled by water, brine, air or any other method. Such a machine is constructed with a number of molds of the section and size usualin the trade. The machine follows somewhat on the lines of candle molding machines, except that the jacket chamber is entirely enclosed, enabling the steam, water or hot air used in the heating or cooling operations to be under pressure. The operating part of the machine described may be mounted on trunnions, longitudinal rotating shaft or pivots.

In order to eject the molded soap from the machine, it is proposed by this invention to so construct the machine, that when the soap is sufiiciently cooled the main body may be revolved about a longitudinal axis to any suitable angle from a vertical to a horizontal position by means of a pinion gearing fed from a central supply or arranged on a revolving platform.

In order that the present invention may be clearly understood and more readily carried into. effect one application is hereinafter described with reference to the accompanying drawings in which Figure l is a sectional side elevation of a machine showing the water box and molds; Figure 2 is a sectional end elevation of said machine;

Figure 3 is a plan view thereof;

Figure 4 is a sectional end elevation of the machine with the body in its ejection position and discharging bars of soap on to a travelling trolley; and

7 Figure 5 is an outside end elevation of the machine showing the operating gear.

As shown and referring to the drawings the sealed body or jacket chamber (1 containing the molds b is mounted on a horizontal trunnion or operating shaft 0 which passes through a hollow core a in the water box and is supported in suitable standards or frames d so that by means of suitable mechanism it can be turned from the normal or vertical position shown in Figures 2 and 5 to the horizontal or preferred ejection position shown in Figure 4. The bars could, however, be ejected vertically if desired. This movement is effected by means, of a double pinion e f which is slidably keyed to, the shaft 0 and is moved thereon as desired by an operating arm or any other suitable m'echanism not shown. The trunnion orv operating shaft 0 is adapted to be turned by suitable means such as by a crank handle 9 and the arrangement is such that when the gear wheel 6 is in the position shown in 'igure 1 in engagement with an intermediate spur wheel h which latter also gears with a quadrant or'section i the water box a and -molds b can be turned through an angle of 90 degrees into a horizontal or discharging position on one side or the other as desired.

After the soap has been into the 'molds, b which are fitted to the chamber a and are heated by admitting air, water, steam or electricity and then cooled by air, water or brine and after the turning operation from a vertical to a horizontal position has been completed, the pinion f on the shaft referred to is thenthrow-n into gear with one j of a pair of wheels 7' 70 operating racks Z connected to a table m to which a number of pistons n,from the various molds b are attached by means of rods 0. The move-' ment of the table m ejects the bars of soap 7) from the molds 6 direct onto a series oftrays g carried either b a travelling trolley suchas r or a frame xed to the machine so that the bars of soap p are delivered ready for packing or stamplng,

ans orsoap crutchers'. W en the soap has een delivered in this manner, the main body of the machine a is returned to the vertical plicated at each end of the machine as areposition, re-filled, and the operation is continued. The wheels 7' and k are'moun'ted on longitudinal shafts .7" and k and are dualso the racks -'Z,with which they engage.

' The molds may be formed with external fins or ribs to facilitate he ting or cooling, and the chambers, jackets ibr pipes may, be fitted with bafiles, diaphragms or retarders to facilitate circulation and thus promote the heating or cooling processes. y Itwill be seen that as the steam, air, and water are admitted to a closedspace in the jacket fi b hey can be used under p'res-' I sure if desired. 1

Provision may or scavenging the molds between the charges, by mechanical process, compressed air or steam jets. j V

- Provision is also made by modification f A the'arrangement described to'charge-or su ally for ejecting liable to warp in the same manner as .bars' cut from slabs I owing to the fact that they are suddenly and evenly cooled throu hout, and furthermore there is not the same oss in evaporat on or weight as with bars cut from slabs, owing to the molded bars-being livered from the molds, with a naturally formed protective skin.

Further a will be appreciated as the bars havingsu'ch a protectiveskin will not without handling,: from they time the liquid soa leaves the soap [20 strained to also bemade for-cleaning e soap bar surfaces through that. b asuitable lockin device they 'can' it at.

molds within saidjbox, 1 mally in position-tomalntam carried by said table stick to the papers in which they are usually and glossy finlsh owing to the aforesaid sudden cooling.

What I claim .is i 1. A soap-molding machine comprising a horizontal shaft, a jacketed mold having one open end carried by said shaft and normally supported with its open end 'uppermost, an ejector fitted in and carried by the wrapped; theyalso have a umform colour mold, means om said shaft for turning the mold and bringing the open-end thereof to a discharging position, and means on said shaft to drive the ejector throu h to the open end thereof in the 1 sition.

2, In a soap-molding machine, the combi= nation of a horizontally disposed. shaft, a sealed box carried by said shaft, a plurality of molds contained within the box and norelivery pothe mold mally in a vertical position with their upper. ends open, a -table normallybelow the.

box, a plurality of ejectors carried by said table and fitted in the several molds, m m on'the shaft for turning thesame and bringing the box and the molds into a delivery position, and means operativelyconnecting the shaft with the table whereby to move the ejectors through the molds toward the open ends thereof inthe delivery position of the molds.

3. In a soap-molding machine, the combination of gears "slidably 'mounted thereon. and conrotate therewith, a sealed box said shaft, a pluralityof molds carried by within said I meshing with said rack and adaptedto be engaged by one of the gears upon the hori- 1 zon'tal shaft whereby to turn the box and the position and vice rsa,"a plurality of plungers and adapte to be actuated by the other gear'upon the horizontal shaft for mom a horizontally disposed shaft,
